My T has run a best of 11.18-11-22 @123-124 mph on race gas 112 octane before alky injection with 50# injectors, translator, 3.5 MAF, 62 series tubonetics, PE front mount intercooler, red armstong pump, adjustable regulator, no cat and the usual buildup on the stock 109 block. I was running an old Jay Carter chip from the mid 90's. I bought a single stage SMC alky kit when they first came out and it was great on the street and ran 12.14 @ 114 mph on just pump gas at the track on street tires with a 2.1-60' with the above mentioned combo the first time out at the track. All this was 5 years ago.
Fast forward. Nothing has changed but I now have a complete real motor (final compression ratio 8.67-1 Weisco pisons, good rods, SS mains, APR studs, 208-208 cam) and trans build up with a new progressive SMC with two #15 nozzles. The iron heads, intake and all the assorted intake hardware have just been cleaned up, same 50# injectors, new 62 turbonetics stage V. Same 3" downpipe that splits into the two 2.5 exhaust pipes it had when it ran 11.18-22. Nothing radical!
I also have two new Jay Carter chips one street and one race chip. Jay has been great.
Car runs great on any chip on the street where you ease into the throttle to control wheelspin but don't go over 20# boost because it will begin to detonate and back out timing no matter where you set the alky kit (and it is coming on and spraying). You can never just open the throttle fully it will detonate. The O2 volts are at 770-810 so the fuel is there but the car is detonating and I don't want to hurt the new motor. All the rest of the numbers on the OTC are in the zone so I don't know where to start. Turbo is spooling quickly.
Took it to the track for test and tune BOP here in G'ville (5 passes total) and tried all three chips to no avail. 12.5 @ 113 is the best it will run @ 19-20# boost running poorly all the way down the track. Put in three gallons of race gas to no avail.
I build boost at the line but you cannot just fully open the throttle at the line and launch it, it will balk. You have to back out and ease into it like on the street to get it to run and pull hard.
Any Ideas?
Anyone ever try race gas in the alky tank instead? Or wouldn't it put enough fuel in?
